SPECIFICATION rc1-maag part of Letters Patent No. 694,645, dated March 4, 1902.

Application filed May 31,1901.

To LZZ whom] t Wray concern: i

Be it known rthat I, FRANK .WALTER How- ARD, a citizen of the United States, residing at the borough of Brooklyn, city and State of New York, have invented an Improvement in Pumps for Fluid-Tanks, of which the following is a specification.

p My invention relates to an improved pump for Huid-storage tanks especially adapted for use with automobiles and other motor-vehicles and from which the feed-tanksof such vehicles are'periodically filled.

My invention is also applicable for fluidstorage tanks for store use or for use in private dwellings and from which vessels, such as lamps, maybe readily filled; and the object of my invention is to provide la vaportight tank of few parts androne readily accessible and in which the parts are altogether removable.

In carrying out my invention I provide a single removable cap forming a support for the barrel of the pump-plunger and for the discharge-pipe and packings atall the joints and an adjustable discharge-pipe and an automatic valve in the headof said pipe normally seated to prevent escape of vapor and the effect of a back pressure.

In the drawings, Figure l is a vertical sec'- tion representing my improved devices, t0- gether with the top and bottom portions of the tank. Fig. 2 is a plan of the operative and removable parts. Fig. 3 is across-section and inverted plan ofthe removable cap at the line a: of Fig. l. Fig. 4: is a sectional plan at y y of Fig. l, and Fig. is a sectional plan at z z of Fig. 1 p

The tank a,of sheet metal, maybe of any desired form. To an opening in` this tank I securely fasten by solder a flanged collar b, interiorly threaded. The removable cap c is provided with a substantially fiat top, and a threaded flange c' is cored out on the under side to provide circular intermediate flanges, and the threaded flange c screws into the flanged collar b, there being a' packing 2 between the flat opposing faces of the parts to assist in forming a vapor-tight joint. Integral with this removable cap c is a threaded Serial No. 62,539. (No model.)

flange c2. The barreld-and the dischargepip/e h are received into the intermediate flanges on the under side of the removable cap and they are securely soldered thereto, and said barrel and discharge-pipe are each provided with a hole l near their point of connection with the cap. ,Y

The barrel d and discharge-pipe 71, extend downward from the removable lcap through the tank to the bottom of the tank, and they are surrounded and connected with a case g of tubular form, which embraces both of said parts, and which case is provided with a bottom plate g', having an opening, and valveplate 3, closing the same.

Within the barrel dis the plunger e and plunger-rodf, and within the 'discharge-pipe h is an adjustable discharge-pipe t', having a packing t" around the same at the lower end to close the opening between the discharge-` pipe and the adjustable discharge-pipe t', so that as between these parts no fluid can pass no matter what the vertical position of the auxiliary discharge-pipe e' may be with ret'- erence to thedischarge-pipe h, as it is possible to raise and lower the adjustable pipe t' for the discharge of the fluid as may be desired. Upon the upper end of the adjustable discharge-pipe vl I provide a head comprising'anozzle cand a valve-pocket k', and from the nozzle 7o extends a pipe 4 to a feedtank or for delivering fluid into a vessel. l A seat is formed within this head at the base of the nozzle and the valve-pocket and at the upper end of the adjustable discharge-pipe for a ball-valve 5. This valve is preferably of metal, and being of some weight normally rests upon its seat. Around the pipe i and screwing into a recess in the upper surface of the removable cap c is a nut 6 of a packinggland, whereby the passage of the pipe t' through the said cap is closed to the escape of fluid and also to the escape of-vapor.

I provide a screw-cap Z, interiorly threaded and screwing upon the threaded flange c2 and the washer 7 between the under surface of the cap Z and the upper end of the barrel d. The plunger-rod f passes through the washer '7 and through the screw-cap Z, and the upper `surface of the screw-cap is recessed to provide a packing-gland, and anut S, surrounding the plunger-rodf, screwsinto this recess to compress the packing and form a tight joint around the plunger-rod to prevent the escape of fluid and vapor.

The upper end of the rodf is provided with a handle 9, and the vertical upward movement of said rod fand plunger e draws the fluid from the tank into the case g and barrel d through the valve 3, and the downward movement of the said rod f and plunger e closes the valve 3 and forces the fluid up the discharge-pipe h and the adjustable pipe i, lifting the valve 5 from its seat into the pocket 7c and escaping by the nozzle 7c and pipe 4. As soon as the movement of the plunger e ceases the ball-valve 5 returns toits seat, preventing the escape of vapor and the effect of any back pressure, and the holes l in the barrel d and discharge-pipe h maintain a balance of the vapor-pressure as between the tank and the inner portions of the barrel and the discharge-pipe with the movement of the parts. From this structure it will be observed that the case g is smaller in diameter than the threaded flange c2 of the cap and that all the parts are connected to the removable cap c and that by unscrewing the cap c from the flanged collar b all the parts may be removed from and taken out of the tank. This facilifates the manufacture of the device, lessens the number of joints, and localizes any possible escape of fluid or vapor. Besides, both the pump and the discharge are adjacent to one another and of simplified form.

I do not herein lay any claim tothe special structure of the case g, its valve 3, and the connection thereto of the barrel (Z and discharge-pipe 7L in themselves.

l claim as my inventionl. The combination with the tank and the flanged collar connected thereto, of a removable cap adapted to be connected to the `flanged collar, a pump device, a dischargepipe and an adjustable discharge-pipe all connected to the said removable cap and extending in part from the cap down into the tank and upwardly from the cap outside of the tank, and a case of tubular form surrounding and secured to the lower ends ot' the pump device and discharge-pipes, substantially as set forth.
